How to extract images from a PDF file?

Syncfusion Essential PDF is the .NET PDF library used to create, read, and edit PDF documents. Using this library, you can extract images from a page or an entire PDF document.

Steps to extract images in PDF programmatically:

1. Create a new C# Console application project.
2. Install the Syncfusion.Pdf.WinForms  NuGet package as reference to your .NET Framework applications from NuGet.org.
3. Include the following namespaces in the Program.cs file.

C#

using Syncfusion.Pdf;
using Syncfusion.Pdf.Parsing;
using System.Drawing;

VB.NET

Imports Syncfusion.Pdf
Imports Syncfusion.Pdf.Parsing
Imports System.Drawing

4. Use the ExtractImages() method that allows you to extract images from a particular page or an entire PDF document.

   //Extract images from first page
   Image[] extractedImages = pageBase.ExtractImages();
   

5. The following C# and VB.NET code snippet shows how to extract images from a particular page or an entire PDF document.

C#

//Load an existing PDF
PdfLoadedDocument loadedDocument = new PdfLoadedDocument(DataPathBase + "sample.pdf");
 
//Load first page
PdfPageBase pageBase = loadedDocument.Pages[0];
 
//Extract images from first page
Image[] extractedImages = pageBase.ExtractImages();
 
//close the document
loadedDocument.Close(true);

VB.NET

'Load an existing PDF
Dim loadedDocument As PdfLoadedDocument = New PdfLoadedDocument((DataPathBase + "sample.pdf"))
 
'Load first page
Dim pageBase As PdfPageBase = loadedDocument.Pages(0)
 
'Extract images from first page
